Labeling transportation

Operations dealing with hazardous materials involve storage, and transport. Space does not permit a detailed account of the topic, except to outline some aspects.10 Some aspects of transportation of hazardous materials consist of regulatory control, classification, packaging and labelling, transport containers, hazards and hazard assessment as well as emergency planning. 

Fig. 5 Dose dependence of P(Lys)-BSA competition on I-labeled P(Lys)-BSA, I-labeled nucleoplasmin, and P-labeled U2 snRNA nuclear import. Nuclear import in 10-lS oocytes was assayed at 45 min after coinjection of the labeled transport substrate with increasing concentrations of P(Lys)-BSA. Normalized transport (relative transport) is expressed as the ratio of competed import, with P(Lys)-BS A to uncompeted import, with BS A.

A good example of a prescriptive approach to quality assessment is the protocol outlined in Figure 15.2, published by the Environmental Protection Agency (EPA) for laboratories involved in monitoring studies of water and wastewater. Independent samples A and B are collected simultaneously at the sample site. Sample A is split into two equal-volume samples, and labeled Ai and A2. Sample B is also split into two equal-volume samples, one of which, Bsf, is spiked with a known amount of analyte. A field blank. Dp, also is spiked with the same amount of analyte. All five samples (Ai, A2, B, Bsf, and Dp) are preserved if necessary and transported to the laboratory for analysis. 

Production and Shipment. Estimated adiponitrile production capacities in the U.S. in 1992 were about 625 thousand metric tons and worldwide capacity was in excess of lO metric tons. The DOT/IMO classification for adiponitrile is class 6.1 hazard, UN No. 2205. It requires a POISON label on all containers and is in packing group III. Approved materials of constmction for shipping, storage, and associated transportation equipment are carbon steel and type 316 stainless steel. Either centrifugal or positive displacement pumps may be used. Carbon dioxide or chemical-foam fire extinguishers should be used. There are no specifications for commercial adiponitrile. The typical composition is 99.5 wt % adiponitrile. Impurities that may be present depend on the method of manufacture, and thus, vary depending on the source. 

The xylene isomers are flammable Hquids and should be stored in approved closed containers with appropriate labels and away from heat and open flames. Limits for transportation by air are 5 L on passenger planes and 60 L on cargo planes. 

Containers less than bulk must bear the red diamond-shaped "FLAMMABLE LIQUID" label. Bulk containers must display the red "FLAMMABLE" placard in association with the UN1090 identification. Fire is the main ha2ard in emergencies resulting from spills. Some manufacturers provide transportation emergency response information. A listing of properties and ha2ard response information for acetone is pubHshed by the U.S. 

Polyacrylamide powders are typically shipped in moisture-resistant bags or fiber packs. Emulsion and solution polymers are sold in dmms, tote bins, tank tmcks, and tank cars. The transportation of dry and solution products is not regulated in the United States by the Department of Transportation, but emulsions require a DOT NA 1693 label. 

Acrylonitrile is transported by rail car, barge, and pipeline. Department of Transportation (DOT) regulations require labeling acrylonitrile as a flammable Hquid and poison. Transport is regulated under DOT 49 CFR 172.101. Bill of lading description is Acrylonitrile, Flammable Liquid, Poison B, UN 1093 RQ. ... 

Caustic soda is classified as a corrosive material by the DOT and DOT regulations and specifications must be followed for handling, labeling, and transportation in containers. Warning labels are recommended for containers of caustic soda solutions and anhydrous caustic soda by the MCA (79). The DOT identification number is UN1824 for 50 or 73% Hquid, and UN1823 for anhydrous caustic. 

The DOT ha2ard classification of formic acid is "corrosive material." A DOT white label is mandatory for transportation. The EC classification is "corrosive."... 

Shipment of hydrazine solutions is regulated in the United States by the Department of Transportation (DOT) which classifies all aqueous solutions between 64.4 and 37% N2H4 as "Corrosive" materials with a subsidiary risk of "Poison". Hydrazine has been identified by both the Environmental Protection Agency and the DOT as a hazardous material and has been assigned a reportable quantity (RQ) of 0.450 kg (1 lb) if spilled. Dmms for the shipment of these solutions must bear both the DOT specification "Corrosive" and "Poison" labels in association with the markings "RQ Hydrazine Aqueous Solution UN 2030." Aqueous solutions of 37% concentration or less are a hazard Class 6.1, UN 3293, Packing Group III and require "Keep Away From Food" placards and labels. 

The ICC classifies all three pentanes as flammable Hquids and requires that they be affixed with a red label for shipping. Because of their high vapor pressures, n- and isopentane are transported in heavy-walled dmms and neo-pentanes are transported in cylinders (see Packaging containers and INDUSTRIAL MATERIALS). 

Concentrations over 8 wt % are classified as corrosive Hquids by the Department of Transportation (DOT). The Bureau of Explosives regulation (132) classifies all solutions containing 20 wt % and greater as oxidizers and corrosives. The product containers must have identifying labels (dmms) or placards (tank cars, tank trailers) indicating that the contents are an oxidizer and corrosive material, UN 2014 or UN 2015. Bills of lading must also be so identified. Tank cars and tank trailers are constmcted from high purity aluminum or 300 series stainless steel. 

U.S. Department of Transportation classification flammable Hquid, hazard label 3.3 DOT/UN /Na shipping number 2521, flammable Hquid. Transport by sea IMDG-code class 3.3, p. 3333, emergency sheet 3—06. Transport by rail and road RID/ADR class 3 Rn 301-31c.
